Rough idle...

[s1ngletracker]

alright... updates (if anyone cares)

-I got a new O2 sensor (it may have been the original and was pretty grimy!)
-cleaned TB (was pretty clean anyway)
-tested ISC (#1 coil is bad, resistance around 60 ohms, looking for another, post if you have one you can sell me) I think this may be the cause of my idle not "catching" on quick slowing of RPMs.
-checked/reset TPS (.90 ohms closed). Looks to be functioning fine.
-Checked EGR, not clogged, looks OK.
-Checked ECU, the caps have been replaced and appear to have been soldered on acceptably.
-I did find a missing stud in my exhaust manifold, and i found a leak on the other side. Need to remove manifold, easy out the stud, and swap on a new gasket. This may be contributing to the bad idle. Thinking about doing a 2G ported manifold swap at the same time... also, does anyone know who makes/sells a good aftermarket O2 housing? Might as well do that too.

Conclusions/further stuff to do:
-I think I may have some vacuum and boost leaks. I realized my car isn't pulling much vaccum at idle, i really hope its not compression but i'm going to test that.
-Plan for tonight/tomorrow is to pressurize the system to check for boost leaks.

Hopefully fixing the leaks will mostly solve my problem.
